TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES H. SEAWELL, of St. Louis, Missouri, haveinvented a new and improved Mode of Constructing an Express-Call, calledCharles H. Seawell's AExpress-Gelb and I do hereby declare that thefollowing is a full and exact description of the same, reference beinghad to the annexed drawing, and

letters marked thereon. l v

The nature of my invention consists in constructing a series of doublesigns, so that the lettered sides may 'be thrown together and the blanksides out when no call is desired, and the letteredsides out and blanksides together when a callis wished. K

To enable others skilled in the art to make and use my invention, I willproceed to a full and exact deseription of the same.

Figure l represents a perspective view of Charles H. SeawelleExpress-Gall.

The letter d represents a square or rectangular f1-ame, with the wires bb b b b passing through from side to side, on which to hang thesign-boards, which may be made of any metallic substance, and'put on thewire similar to a common hinge, as seen at a a a a a.

c cl c c c are the front signs, lettered on their front sides with thenames of the various companies.

c c c c c' are the rear signs, lettered on their fronts with letters tocorrespond to the front ones. These pairs, being hung on the wires b b bb b, can he thrown with their blank sides together and their letteredsides. out when a call is needed, and thus they may he seen from bothsidesv of the frame. i

When the signs are not to be used, their blank sides are out, as seen inNos. l, 4, 5; when they are used, they will appear as seen in Nos. 2, 3.

Of course I do-not claim, as new, the signs; but

What I claim, and for which I ask Letters Patent of the United States tohe granted me, is-

The signs c and c', placed in pairs on a pivot-wire, b, and arrangedwith calling-signs on one face, but blank on the reverse, so that thecall shows on both sides when it shows at all, as described.

G. H. SEAWELL.
